I am curious to know how many units of each model does Audio Research Produce. For instance, anyone has na idea how many RFE 5 SE or REF150 were produced? I believe this number must be diffrent from unit to unit, but would like to get a general idea. For instance, when they decuide to launch a new product, like the Ref 6, what is their aim of selling units or aim of production. Does anyone have na idea?
